   has_Tachycardia

Save that and save the GLIF file. Let's test what we have so far.

Go File, Load xml Test Data and choose GLIF_TutorialSix.xml 

Click on the Run button. What happens? Yes the patient state gets a little green arrow in it and the link arrow from it to the next action step should remain green ( ie it is running). Click on the green arrow and you can see the value being persisted for the patient state as a result of the GELLO that has been executed.

Now we will re-use that intermediate persisted state in a Decision. Add a decision node and call it 'Tachycardia and aged over 75?' Flow the decision out to two action nodes.

In the Yes link, use this code:

   Context GLIF_VMR::GLIFDecisionNode

   Let q: String = "Is patient tachycardic and aged over 75yrs?"
   Let aWeight: Integer = 50
 
   Let isTachycardic: Boolean = GLIFNodes.patient_state_by_name('tachycardic?')
   Let age: PQ = factory.Now() - vmr.patient.dob 
   Let ageInYears: PQ = age.convert('yr')

   Let result:GLIFDecisionResult =
 
     if not vmr.vitals.pulseRate.oclIsDefined() and not vmr.patient.dob.oclIsDefined() then
       GLIFDecisionResult{Question = q,Answer = unknown, Reason = "No pulse rate or age information",Weight = aWeight}
        else
          If isTachycardic and ageInYears >= factory.PQ(75, 'yr')
            then
            GLIFDecisionResult{Question = q,Answer = true, Reason = "Patient is tachycardic and aged over 75 years",Weight = aWeight}
          else
           GLIFDecisionResult{Question = q,Answer = false, Reason = "Patient is not tachycardic and aged oiver 75 years",Weight = aWeight}
        endif
     endif 
 
    result

and I will leave it you to put the corresponding code for the 'No' link.
